c++: Diagnose bogus variadic lambda. [PR97358]

If the lambda has a capture pack, it cannot be used unexpanded within the
body of the lambda.  If you want to expand the pack across multiple lambdas,
don't capture the whole pack.

gcc/cp/ChangeLog:

PR c++/97358
* pt.c (check_for_bare_parameter_packs): Diagnose use of
capture pack.

gcc/testsuite/ChangeLog:

PR c++/97358
* g++.dg/cpp0x/lambda/lambda-variadic11.C: New test.
